Background: This study aims to assess the effect of needle distance of arteriovenous fistula (AVF) cannulation on haemodialysis adequacy based on KT/V.
Materials And Methods: This study was a parallel-group, randomized controlled trial. Patients who met the inclusion criteria were divided into two groups with 3 and 6 cm needle distances using block randomization. Data acquisition transpired through a comprehensive checklist encompassing demographic variables such as age and sex, alongside clinical metrics comprising actual weight, dry weight, average dialysis duration, fistula longevity, and KT/V rate.
Results: A total of 42 haemodialysis patients were enroled in this investigation, with 21 allocated to the 3 cm needle distance group and another 21 to the 6 cm needle distance group. The mean post-haemodialysis KT/V values for the 3 cm and 6 cm needle distance groups were 1.25 (SD=0.25) and 1.42 (SD=0.24), respectively, demonstrating a statistically significant difference (<0.001). While there was no significant difference in the average pre-haemodialysis and post-haemodialysis KT/V values within the 3 cm needle distance group (=1.93, =0.068), the corresponding values for the 6 cm needle distance group exhibited a notable discrepancy (=9.66, <0.001).
Conclusion: In general, a needle distance of 6 cm between arteriovenous points yielded superior enhancements in dialysis adequacy compared to a 3 cm needle distance following haemodialysis. Consequently, health administrators and policymakers may consider instituting efficacious interventions to scrutinize the care and therapeutic protocols for haemodialysis patients, involving the development of policies and applications.

This study aimed to evaluate and compare the efficacy of single-puncture techniques in temporomandibular joint (TMJ) arthrocentesis for the management of disk displacement without reduction (DDwoR). A total of thirty-six patients diagnosed with DDwoR were randomly and blindly assigned to two treatment groups (N = 18 each): Group 1 underwent TMJ arthrocentesis using a concentric needle-cannula system with protrusive movements, while Group 2 received TMJ arthrocentesis with a concentric needle-cannula system but without protrusive movements. The following variables were recorded and compared between the groups: maximal interincisal distance (MID - mm), patient pain perception (visual analogue scale - VAS [0-10]), and operation duration (OP - minutes).

Electrospinning can be used to prepare membranes with characteristics for biomedical application. In this work, the electrospinning conditions for the fabrication of membranes based on polymers extracted from natural sources such as chitosan and collagen were optimized (injection flow, injection volume, distance from the collector to the neddle, needle size and voltage). Specifically, four formulations were prepared with pure chitosan and mixtures of collagen (purified or hydrolyzed) and agarose.

Electroacupuncture (EA) is one of the most commonly used methods in acupuncture and has a good effect on pain, depression, sensory movement disorders, and other diseases. The effectiveness of EA is influenced by many factors, such as the accuracy of acupoint selection, the duration and course of EA treatment, and EA parameters. However, it has rarely been discussed whether the positive and negative electrodes of the EA instrument with acupoints at different locations and distances have an effect on the curative effect.

Objectives: Vascular access thrombosis (VAT) is a common complication in patients with end-stage renal disease (ESRD), significantly impacting hemodialysis efficacy and patient survival. Currently, temporary dialysis access is typically established deep vein catheterization (VC), however, this method is highly invasive and associated with risks of infection and other complications. This study aims to explore the feasibility of using direct anastomosis indwelling needle puncture (DAINP) for temporary dialysis access.
